Scientists have found out where the red giants disappeared from the center of the Milky Way

Countless stars lie within 1.6 light years of the Milky Way's central black hole. But in this

In a densely populated area, there are fewer red giants—large, cool, bright stars—than there should be. Scientists have discovered the reason for this anomaly in a new study.

Astrophysicists have a new theory whythe center of the Milky Way, the red giants have disappeared. Scientists believe the supermassive black hole Sagittarius A * released a powerful jet of gas that ripped off the outer layers of the red giants. This turned the stars into smaller red giants or hotter and bluer stars. Such a theory was put forward by Michal Zayachek, an astrophysicist at the Polish Academy of Sciences in Warsaw, and his colleagues in an article published in the Astrophysical Journal.

Today Sagittarius A * is calm, but scientists suggest that the black hole came to life about 4 million years ago, when something fell into it and destroyed the red giants in the center of our galaxy.

The gas disk around the black hole fired a powerfulstream of material into its star-studded environs. Such jets of radiation mostly affect large red giants. They are especially vulnerable due to their large size and thin gaseous envelope.
